Final answer:

To solve for the time it takes for a turntable to reach its final rotational speed, we can use the equation Δω = αΔt, where Δω is the change in angular velocity, α is the angular acceleration, and Δt is the time taken.

Step-by-step explanation:

The given question is asking for the time it takes for a turntable to reach its final rotational speed. To solve for this, we need to use the equation that relates rotational quantities:

Δω = αΔt

Where:

  • Δω is the change in angular velocity (from initial to final)
  • α is the angular acceleration
  • Δt is the time taken

In this case, since the final angular velocity is not given, we can assume it to be zero, as the turntable comes to a stop. The question does not provide any other specific values, so we cannot directly solve for the numerical value of the time taken.
